KISSsoft & KISSsys: Gear up your design Vikas Grover Product Manager - KISSsoft Kadkraft Systems, Chandigarh
How to make KISSsoft implementation, a success!
Challenges for a Gear Company Unawareness about the changes in Standards of gears and bearings Home made programme Delayed response to the customer Expensive and time consuming physical prototypes & tests Dependent on vendors Cutters, Oil, Bearing etc. Design documentation Not meeting standard & non-comprehensive Error prone manual calculations
Benefits of using KISSsoft Gear geometry Gear strength based on globally accepted ISO/DIN/AGMA/VDI standards Reduction of design time by over 90% Optimisation Loaded tooth contact analysis and suggestions for the modification required in design Shaft modelling and rating Bearing calculations Automatic generation of accurate 2d profiles and 3d models System level calculation Optimisation of lifetime & quick simulation of different gearbox configuration Catalogue generation
KISSsoft : Gear geometry Gear geometry Consider multiple tools for gear geometry Include microgeometry / modifications including topological modification Export manufacturing data Ring gear based on shaping cutter geometry Consider protuberance tool
KISSsoft : Gear Strength Gear strength and life rating Root strength / pitting, static rating, ISO 6336/DIN3990 /AGMA/VDI Micropitting method A / B, ISO TR 151544 Scuffing rating along ISO/TR13989, DIN3990-4, AGMA925 Ring gear strength VDI 2737 Khbeta along ISO6336-1, Annex E Wear calculation along Plewe method
KISSsoft : Optimization Gear sizing Software can size from basic inputs like torque/power, speed along with the ratio Optimization gear pair with respect to - Weight - Strength - Contact ratio
KISSsoft : Loaded tooth contact analysis Gear analysis For parallel or planetary stages Consider different microgeometry definitions Contact stress, transmission error, Oil film analysis
KISSsoft : Shafts Versatile shaft modeling and rating Static / fatique rating along DIN743, FKM and AGMA 6101-E08/6001-E08 For nominal and extreme load and with LDD Automatic connections between shaft deformation and tooth contact analysis
KISSsoft : Bearing Highly detailed bearing analysis Basic, basic modified, reference and modified reference rating Load distribution and contact stress calculation For single load and LDD Thermal rating, friction and power loss Own definitions of rolling elements correction
KISSsoft : 2d & 3d models Software can generate accurate 2d profile and 3d model 2d profile save as.dxf file format 3d model save as.step and parasolid file format
KISSsoft : Systems modeling System analysis with KISSsys Any kind of gearbox kinematics including compound, differential, CVT and Flexpin system With or without main shaft model LDD on complete system level Output reports ready for certification documentation Includes scripting / programming language LTCA including non linear bearing stiffness, non linear shaft deformation, housing deformation, planet carrier torsion
ROI of KISSsoft Cost Parameter Cost per annum (INR) Cost of one engineer to the company 6,00,000/- Benefits Cost of the software 15,00,000/- Payback of the software = Productivity/Cost in months Ability to design complex transmission 10% of your turnover, which has higher profitability. (For each 50Cr. Of business, 5% of additional margin) Enhancement of company s reputation 8-9 months Engineers Productivity Enhancement 4Xtime 24,00,000/- 25,00,000/- Priceless
Suggestions for implementation Selection of proper modules - omitting some modules may severly restrict the utlilisation or design capability Use of network license to increase the productivity - Flexibility of use, dongle loss/damage Proper implementation plan - Set milestones with 'What is current' Cross- check the results manually before full-rollout of KISSsoft Company should invest in ISO/DIN/AGMA Gear Standards Involvement of manufacturing people Design should specify manufacturing/cutter/tool information Bearing selection - try for cheaper bearings with same service life
